So you’ve heard intrauterine devices are like, the “it” form of birth control — but what exactly is an IUD? Will it worsen your period? Will the metal (is there metal?) conduct electricity during a thunderstorm? As part of her new women's health education initiative with CEO of WomanCare Global Saundra Pelletier, actress Jessica Biel premiered a "Funny Or Die" series with friends Whitney Cummings and Joy Bryant to clear up any misconceptions surrounding birth control. And this particular video takes on IUDs.

First, Biel points out that there are two types of IUDs: hormonal and non-hormonal. Mirena is an example of a hormonal IUD that releases a small amount of progesterone into the uterus each day, which is how the device prevents pregnancy. Dr. Sara Kennedy, an obstetrician/gynecologist based in Oakland, Calif., reported for Bedsider that this is compared to birth control pills, which release hormones into the whole body. Because Mirena releases progesterone and not estrogen, this brand of IUD has reportedly led to fewer hormone-related side effects.

ParaGard, on the other hand, is a non-hormonal, copper IUD that’s associated with heavier, longer, and crampier periods during the first few months after being inserted by your doctor or physician, Kennedy said. The copper filament that’s wrapped around the T-part of the device is how it prevents pregnancy, and Kennedy said that it’s the only "super-effective non-hormonal birth control method around."

“Do you ever get nervous about having metal in your body with a storm out,” Cummings asked Biel. “That’s how I think Superwoman started.”

Not quite: Superwoman gained her powers from a blood transfusion. And since IUDs are mostly plastic, they’re poor conductors for electricity. That also means it’s not likely to “erode” inside your vagina. It's perfectly safe for a woman to go outside if she chooses to get an IUD.
